One 20 (low serial number, IIRC) would spin without much warning in
thermal or landing flap and always in the same direction (over the top
if I was turning the opposite way), the other would do so only in
landing flap, both seemed a bit twitchy at times. I suspect Schleicher
was still learning how to build glass gliders in a repeatable fashion
during the 20 production run, the 20B/C show the benefits of experience
(plus reduced landing flap travel)...

Curiosity: have you any idea what the serials were for those 20s?
Mine was 20034, so fairly early...

Other significant sources of variability are rigging of flaps &
ailerons, type & condition of seals... and of course now more than
half the 20 fleet flies with winglets of one sort or another, these
make a difference too (especially the odd installation with more toe
on one side than the other).

You really do need to treat these ships as individuals. *My 20B is a
pussycat in #4 and L, it's a little sharp in #3. *I fly it at 90% aft,
with winglets. *It flies straight, the spin behavior is symmetric...
but it does have a eccentric lift pin that someone installed to get it
that way.

Question for Dan: when you swapped ships with the 20B pilot, how much
different were you two in weight? *Your story could be explained
rather neatly if you were a bigger guy than your friend. *I haven't
flown a 6. *Tried to buy one, but the owner wasn't ready to sell. *I
ended up with the 20B a few weeks later, have not regretted this.
Cockpit, controls, landing flaps, landing gear and wheel brake are all
better or a lot better on the 20B. *However it's certainly true that
the 20 flies best if you keep the roll rates about 1/2 of maximum. *At
high aileron deflections, she gets a little draggy. *Not sure if I
want to fly a 6... I'm pretty happy with my ship, want to stay that
way!

Evan, I swapped with Tom Serkowski (5Z) and I think it was a 20B
(stiff wings rather than floppy). I'm a bit taller than Tom but I
think we're about the same weight and we both flew dry. After
landing, I asked him what he thought and he held up the index finger
of one hand and placed the palm of the other hand down on it
indicating balancing on the point of a needle. My reply to his
question was that I thought the 20 was on rails, meaning it was
difficult to roll. I'm sure that's because of the difference in
handling qualities of the two - the LS-6a being extremely light on the
controls.

Hope that answers your question.
